Change log

Archarodim:
    - - Removed LibStub from the .pkgmeta since it's embeded as a hard copy.
    - Added LibStub in X-Embeds in the TOC (why wasn't it there already?)
    (The hardcopy was introduced when Blizzard broke optional deps loading order at some point in the past)
    - - First step converting to Ace3: replacing "AceOO" by "LibOOP", this is done for the LiveList objects only for now.
    - - Removed the 'Ignore stealthed units' option that is useless since several years.
    - Added an option (localization needed) to just show stealth status instead and fix its update.
    - Removed a comment containing lyrics from a NIN song (Closer from TDS) I was listening while coding a while ago... (it could have been misunderstood)
